World number three Suzann Pettersen underlined her class with a dominant display on the final day of the Ladies Irish Open at Portmarnock Links.
The Norwegian fired a closing round of 67 for an 11-under total of 205, five better than compatriot Marianne Skarpnord.
Pettersen began the final round one stroke ahead of New Zealand's Lynn Brooky but a birdie to the Kiwi's bogey at the second hole extended her lead to three.
The 27-year-old from Oslo knocked in three birdies on her front nine, with another three on the back nine.
She carded just one bogey, at the 341 yard par four 14th hole where she hit her second shot into the front greenside bunker.
"It was windy and challenging so I'm very happy with my performance," said Pettersen, after securing her ninth career title.
Skarpnord got within one stroke of Pettersen after an eagle at the 460-yard par five 12th hole where she played her approach shot to within 18 inches of the cup. She birdied the third and fourth holes going out, but bogeyed the 17th and 18th for a closing 70.
Brooky shot a final round 73 for third place on four-under-par, which was her best finish of the season.
Spain's Tania Elosegui, first round leader Federica Piovano from Italy and Germany's Martina Eberl shared fourth on three-under-par.
US Solheim Cup star Morgan Pressel got the hang of the greens on the final day and shot six birdies for a 66. She shared seventh with Wales' Becky Brewerton, Spain's Emma-Cabrera Bello and Sweden's Maria Hjorth, all on two-under.
Claire Coughlan-Ryan was the best of the two Irish players who made the cut. She holed her second shot for eagle at the second hole and shot 74 for a share of 43rd place.
